Abstract
Description
Im Ruhe-, Pflege- und Rehabilitationsmöbelbereich werden gepolsterte Sessel und Stühle verwendet, die durch den Einbau von mechanischen Verbindungsteilen sich so gegeneinander verstellen lassen, daß sie sich aus einer normalen Sitzposition in eine geneigte bis liegende Position mit gleichzeitigem Hochlagern der Füße verstellen lassen. Das kann mit elektrischen Linearmotoren oder durch Gewichtsverlagerung auf der Sitzfläche geschehen.In the rest, care and rehabilitation furniture area Upholstered armchairs and chairs used by the Installation of mechanical connecting parts can be adjusted against each other so that they come from a normal sitting position in an inclined to lying position Position with the feet raised at the same time have it adjusted. That can be done with electrical Linear motors or by shifting weight on the Seat happen.
Dabei sind die die Verstellung bewirkenden (meist als Scherenkonstruktion ausgebildeten) Teile nur Verbindungen der einzelnen Polsterteile und werden entsprechend bei Benutzung beansprucht. Da es meistens Stahlblechstanzteile sind, werden diese durch Nietungen beweglich verbunden. Diese Verbindungen stellen die Schwachstellen eines mechanischen Sessels dar, die zu Schäden neigen.The ones causing the adjustment (mostly as Parts designed only for connections of the individual upholstery parts and are accordingly Use claimed. Since it is mostly Are stamped sheet steel parts, these are riveted movably connected. These connections provide the Vulnerabilities of a mechanical armchair represent the Damage tend.
Der Erfindung liegt die Aufgabe zugrunde, eine Mechanik zu schaffen, die alle notwendigen Sitz-, Ruhe-, Liege- und Stehpositionen ermöglicht und die eine in sich stabile Einheit (Korpus) darstellt. An diese sollen die Polsterteile in einfacher Art angeschraubt werden können.The invention has for its object a mechanism to create all the necessary sitting, resting, lying and standing positions and the one in itself represents a stable unit (body). To these should Upholstery parts can be screwed on in a simple manner can.
Dieser Korpus soll auch ohne Polsterungen alle möglichen Funktionen erfüllen.This body should be all possible even without upholstery Perform functions.
Die Lösung dieser Aufgabe sieht eine Erfindung vor, die aus drei gegeneinander beweglichen Hauptteilen aus Aluminiumguß besteht. An dem Mittelteil ist der obere Kippschemel (Auflage für die Sitzpolsterung) mit einer Verschraubung -1- Fig. 1 kippbar gelagert. Fig. 2 und 3The solution to this problem provides an invention which consists of three mutually movable main parts made of cast aluminum. On the middle part the upper tipping stool (support for the seat upholstery) is tiltably mounted with a screw connection - 1 - Fig. 1. Fig. 2 and 3
Der untere Teil ist mit dem Mittelteil durch einen Scherenmechanismus in der Art verbunden -2-, daß bei einer Differenzbewegung zwischen diesen Teilen das Mittelteil nach oben bewegt und gekippt wird, daß ein sich auf dem Sitz befindlicher Mensch ohne eigene Kraft aus der Sitzposition in die Stehposition gebracht wird. Dabei ist der theoretische Drehpunkt -3- das Kniegelenk des Menschen. Fig. 4The lower part is connected to the central part by a scissors mechanism in the type - 2 - that in a differential motion between these parts, the middle part moves upwards and is tilted so that one under on the seat person without its own power from the sitting position into the Standing position is brought. The theoretical pivot point - 3 - is the human knee joint. Fig. 4
Alle drei den Korpus darstellenden Aluminiumgußteile können gegeneinander durch einen oder mehrere elektrische Motoren, bzw. der obere Kippschemel auch durch Gewichtsverlagerung, bewegt werden. Fig. 3 und 4All three cast aluminum parts representing the body can be moved against each other by one or more electric motors, or the upper tipping stool can also be moved by weight. FIGS. 3 and 4
Auch stellen jeweils das Mittelteil und der obere Kippschemel Fig. 5 bzw. das Mittelteil mit dem Unterteil Fig. 6 eine voll funktionsfähige Einheit dar. Mit der Kombination Fig. 5 kann ein Ruhesessel (Fernsehsessel oder Relaxsessel) hergestellt werden. Die Kombination Fig. 6 ist für eine Aufstehhilfe geeignet. Zusammen ist die Mechanik für einen Ruhe-Aufstehsessel geeignet.The middle part and the upper tipping stool Fig. 5 and the middle part with the lower part Fig. 6 each represent a fully functional unit. With the combination Fig. 5, a recliner (TV armchair or relaxation armchair) can be produced. The combination Fig. 6 is suitable for a stand-up aid. Together, the mechanism is suitable for a stand-up chair.
Um weiter Funktionen für die Anwendung zu erhalten, wird nur der beim Kippen der oberen Sitzauflage entstehende Differenzwinkel zum Mittelteil -Y- verwendet. Fig. 5In order to obtain further functions for the application, only the difference in angle to the center section -Y- that occurs when the upper seat cushion is tilted. Fig. 5
Beim Kippen des Sitzschemels bewegt sich automatisch eine Scherenkonstruktion in der Art, daß eine Auflagepolsterung aus einer im Sessel integrierten Position ausfährt und die Beine in eine Hochlagerung bringt.When the seat stool is tilted, one moves automatically Scissor construction in the way that a Upholstery upholstered in an armchair Extends position and legs in a high position brings.
Eine gewünschte Rückenlehnenverstellung -X + Y- kann ebenfalls aus dem Differenzwinkel der beiden Teile bewirkt werden. Fig. 7A desired backrest adjustment -X + Y- can also be achieved from the difference in angle of the two parts. Fig. 7
Durch die Verwendung von Aluminiumgußteilen wird die notwendige Stabilität in allen Ebenen erreicht.The use of aluminum castings necessary stability achieved in all levels.
Bei der Verwendung dieser als Korpuskonstruktion ausgelegten Erfindung kann der Anwender den gesamten Bedarfsbereich bei der Herstellung von Ruhe-, Liege- und Aufstehsesseln bzw. Stühlen abdecken.When using this as a body construction designed invention, the user can use the entire Required area in the manufacture of resting, lying and cover stand-up armchairs or chairs.
